Been there, doing that. My firsts (twins) are due in less then two months. Might I suggest Jolly Rancher Fruit n' Sour Hard Candy as part of your EDC. They really work well for nausea, and can be stored at ambient while Preggo Pops cannot.

Also, prep for what the relaxin is doing to your joints. As you found out this morning, you're turning into Gumby. Ace bandages or athletic tape will help with the sprains. The T-handled (i.e. Komperdell Walker Antishock) walking sticks can take a lot of weight off your knees. Add one (or more) of those to your GHB.
